Product information

 

Your mobile socket with integrated mains priority circuit!

The conversion of the 12 V on-board battery current into pure 230 V alternating current (pure sine wave) is the task of this inverter. Smooth battery-to-AC switching ensures intelligent mains priority as soon as your vehicle is connected to the normal grid. The energy-saving smart standby function is activated automatically when no load is applied. The inverter also switches on again automatically as soon as the pre-set "wake-up" area is reached.

The DSP 1812T Comfort Sine Wave Inverter is designed to reliably operate electrical equipment up to a maximum load of 1,800W. Due to the large input voltage range, this is particularly suitable for modern alternators of the current EURO-6 vehicle generation.

Possible damage to terminals prevents the integrated protection circuit in the event of overload, overheating, overvoltage or undervoltage. The outstanding price-performance ratio of this inverter is additionally rounded off with a user interface for easy operation and control, a CI bus compatibility for easy integration into your vehicle network and a load and temperature-controlled, low-noise fan.

The function of a mains priority circuit briefly explained

Basically, a mains priority circuit ensures the reliable separation of two input voltage sources; for example the 230 V shore power grid and the inverter (see below) of the on-board battery. This ensures that both circuits cannot be accidentally parallel connected, which could have fatal consequences. Normally, the installed on-board electronics automatically recognize which power source is connected. If you are connected to shore power, this then usually has "priority" (before the on-board battery). Without a shore power connection, the device switches to the on-board battery as the power source.

The inverter

Inverters are used to convert DC voltage (12 V or 24 V) into 220/230 V AC voltage of 50 Hz. This is necessary if you are on pitches without shore power supply and want to use electrical devices in your vehicle that do not have a 12/24 volt connection. This could be, for example, a hair dryer, a coffee maker or a battery charger.

When choosing the right device, the maximum "nominal power" (or also called "effective power") is important. This "rated power" is given in watts. Every electrical device requires a certain "rated power" to operate. There are inverters that provide 1000, 2000 or 3500 watts of "nominal power". But also some that can "only" deliver 100, 150 or 350 watts.

Depending on the model, the hair dryer from the domestic bathroom can take up 2200 watts at the highest power level. With an inverter that can, for example, "only" deliver 1500 watts, this hair dryer will not work. But if you don't want to do without such a hair dryer away from any shore power supply, you would do well to adjust the performance of your inverter to the energy requirements of your 220/230 V devices. Even if several devices have to be in use at the same time, the sum of the total energy requirements must be taken into account in such cases.

An inverter is one thing. The board battery is the other!

Even the most powerful inverter can only "work" as long as the on-board battery allows with the amount of energy available. An inverter "only" converts the type of voltage, but does not generate any energy itself. The power supply, which is independent of shore power, is limited and depends exclusively on the energy stored in the on-board battery. A common on-board battery has a storage capacity of 100Ah (ampere hours). This means that such a battery can provide 100 amps for a period of one hour.

Said hair dryer with 2200 watts needs about 9.5 amperes at 230V voltage and a full continuous output of one hour. So if you (theoretically) just let this hair dryer run on, the on-board battery would be empty after another 9 hours. Therefore, the performance of the on-board battery(ies) installed in the vehicle should generally be taken into account when considering which 220/230 V devices are actually indispensable with an independent power supply. Also taking into account that a battery should not be discharged more than 50% in order to protect it.

Sine Wave - the difference between a "modified" and a "pure" sine!

Electrical devices, which are also used at home, need a "sine wave" (a current signal) that is as identical as possible for their function on the go. An inverter (as well as a voltage converter) emits a "modified" or a "pure" sine wave, depending on the model. The "pure" sine wave comes very close to the current signal of the domestic 230 V power supply, which means that most electrical devices can be operated from home in the caravan or mobile home. With a "modified" sine wave, it is not uncommon for devices such as a laptop, an electric toothbrush or water pumps do not work.
